title: [Tissue and urokinase plasminogen activators (t-PA, u-PA) and their inhibitor PAI-1 in blood of patients with laryngeal neoplasms].
abstract: Plasminogen activators and inhibitors regulate a variety of physiological and pathological processes involved in tissue morphogenesis, cell differentiation, migration, cancer cell invasion and metastasis. Several reports have shown the decrease of fibrinolytic activity in the blood of cancer patients. In this study we measured the concentrations of tissue plasminogen activator (t-PA), urokinase plasminogen activator (u-PA), activity of plasminogen activator inhibitor type 1 (PAI-1) and euglobulin lysis time (ELT) in the blood of 20 men aged 42-75 years old with planoepitheliale larynx carcinoma, and 10 healthy persons in similar age. In this study the mean values of t-PA, u-PA concentrations, PAI-1 activity and ELT in the blood of patients with larynx carcinoma were similar to the examination results of healthy persons, but 40% of our cancer patients have increased activity of PAI-1.
